TAN K-VALVE.

SPECIFICATIQON forming part of Letters Patent No. 543,570, dated July 30, 1895.

' Application led November 24, 1894:- Serial No. 529,832. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, DAVID CRAIG, of Melrose, county of Middlesex, State of Massachusetts, have invented an Improvement in Tank- Valves, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like partys.

This invention relates to tank-valves or flushing devices for Water-closets of the slowacting kind, and has for its object to improve and simplify the same in many particulars; and the invention consists in details of construction of the parts, as will be hereinafter more particularly set forth.

Figure l shows in longitudinal vertical section a tank-valve embodying this invention; Fig. 2, a plan view of the parts shown in Fig. l, and Figs. 3, 4, and 5 sectional details to be referred to,

The tank a may be of any suitable shape and size, provided with an inlet (not shown) A fitting (herein represented as a T c) is permanently connected with an inner tube h', arranged Within the outlet-pipe b, and is secured to said outlet h and a bayonet or other joint, and to the upper end of said T-iitting a collar c is con;l

nected, the vupper end of which is concaved or recessed to form a seat for a ball/d.' The ball d is contained within ac ,nndrical pipe d', the internal diametelr which is substantially the Samaras/the diameter of the ball el, so that Said ball can move from end to end of said pipe slowly, bearing frictionally against the interior of the pipe. A strap or collar cl2 embraces said pipe d near one end, the lower part of said strap or collar being pivotally connected to a stud d3, preferably made vertically adjustable in an arm d4, secured to the collar c-as, for instance, it may embrace said collar.

ing ball d may be seated in the upper end of the collar. A yoke e is loosely placed upon and so as to partially embrace the pipe. d near the lower end thereof, the arms of said yoke projecting downward and engaging the projecting portion of the ball, as best shown in Fig. 3. This yoke is prevented from lateral movement on the pipe by suitable ribs 2O or otherwise. A cord 2 is attached to said yoke, passing up over a pulley c, thence over a pulley 4, and then down within convenient reach of the user, and by pulling said cord the yoke e is rst raised independent of the pipe d', itsV arms lifting the ball d away from its seat, and then said arms engage the pipe and raise it on its pivotal connection, so that the ball d is free to pass tothe other end of the pipe by gravity.

The tank is supposed to be filled with water to the point above the pipe d even when said pipe is raised by the action of the cord. Each end of the pipe d is open and provided with a clack-valve ff', the valve f being pivoted at f2 at'a point above its center, so that when the pipe d is raised the lower part of the valve turns into Athe pipmand/ the valve f' being pivotedfat f3 at its top and prdv'i`dedalso at-fthe' top with an inturned arm or offset vffprovided with an adj listing-screwf5, which, by striking the top of the pipe d', limits the distance the valve f can open. The lower -end of the valve f has an adjusting-screwf, by which the closing of the valve can be regulated, said screw striking against the end of the pipe d. Bypulling the cord 2 the pipe d is raised, and the ball d, passing along the opposite end ofthe pipe, bears upon or against the valvef. At such time the water passes through the outlet-pipe of thetank, flushing the closet. By releasing the tension upon the cord 2 the pipe d Aimmediately resumes its normal position, bearing upon the collar c; but the water continues to pass through the opening in said pipe through which the ball projects until the ball returns, closing said opening and becoming seated in the collar.

The ball in returning to its normal position at the lower end of the pipe d moves frictionally along the'pipe against the pressure of the water in front of it, and owing to the adjustment of thevalve f the water enters at that end of the pipe slowly, so that theball IOD supplementary means for filling the bowl,`

which I desire to be understood is only used in cases of necessity, owing to the additional expense of providingit. This supplementary filling device consists ot' a pipe g, connected with the T-iitting below the collar c, the outer end of said pipe being upturned and formed with a seat at the end for a ball g similar to the ball d, and a cylindrical pipe g2 is pro,- vided, which contains said ball, it having a strap or collar g3 (see dotted line, Fig. l) embracing it near its opposite end, which is pivotally connected to an adjustable stand g4 on the pipe g, or it may be otherwise supported. This pipe g2 is constructed substantially the same as the pipe d', having clack-valves at each end,one of which is adjustable to regulate the inflow of water, and as a means of raising the pipe to cause the ball to leave its seat and pass to the other end of the pipe, and thereby expose the open end of the pipe g, I have herein provided the pipe di with a lateral projection it, having a latch or dog 71.',which, as the pipe d is raised, passes by a projecting arm n2 on the pipe g2; but as the pipe d is returned to its normal position said dog n' engages said arm n2, raising the pipe g2. The arm n2 is made of suitable length, so that while it may be engaged by the latch or dog n during the return movement of the pipe d it permits said latch or dog to slip oit just as said pipe fil tesumes-its`"iormal position, thereby permitting the pipe g2 to thereafterresume its normal position. The ball g of said supplementarypipe resumes its normal position just after the ball d resumes its seat, so that the results desired may be eftectually carried out.

The tank herein shown is also provided with an overliow-pipe which, in itself, I believe, possesses elements or features of novelty. It consists in an overlow-pipem, the lower end of which is connected with the T-itting and the upper end of which projects above the ordinary water-level. This pipe is bent at substantially-right angles, as shown in Fig. l, and at the bend is contracted, as at m', and provided with a seat for a ball m2, which is contained in a short branch pipe or other form of receptacle m3, leading from the pipe opposite the valve-seat therein. The ball m2 normally electually closes the overtlow-pi pe, so that there is no opportunity for the air to enter and cause a rattling or whistling noise when flushing the bowl or at other times; but in case the water in the tank rises above the upper end of said overliow pipe it passes down said pipe, moving the ball m2 out into its branch or receptacle m3, and thereby escaping. A suitable air-veut pipe m4 is provided for said branch or receptacle m3.

I claiml. In a tank valve, the combination of an outlet pipe, a ball valve controlling the passage therethrough, a cylindrical pipe containing the ball, which latter snugly lits its interior, said pipe being pivoted at one end, and provided at its lower side at the opposite end with an opening through which the ball'projects while closing the outlet pipe, a valve controlling the passage through said pipe, which when open permits the ball to move quickly, and when closed or partially closed, causes it to move slowly, and a cord connected with said pipe, substantially as described.

2. In a tank valve, the combination of the outlet pipe and ball seated at its upper end, a cylindrical pipe containing said ball, which latter snugly lits its interior, said pipe being pivoted at one eud,and having an opening at its lower side at the opposite end, through which the ball normally projects, the adjustable valve f', and cord 2, substantially as described.

3. In a tank valve, the combination of the outlet pipe and ball seated at its upper end, a cylindrical pipe containing said ball, which latter snugly fits its interior, said pipe being pivoted at one end, and having an opening at its lower side at the opposite end, through which the ball normally projects, the adjustable valve f', a loose yoke e, and cord 2, su b stantially as described.

4. In a tank valve, the combination of the outlet pipe and ball seated at its upper end, a cylindrical pipe containing said ball, which latter snugly fits its interior, said pipe being pivoted at one end, and having an opening at its lower side at the opposite end, through which the ball normally projects, the adjustable valve f and the valve f, and cord 2, substantially as described.

5. In a tank valve, the combination of the outlet. pipe and ball seated at its upper end, a cylindrical-pipe containing said ball, which latter snugly iits""i-ts interior, said pipe being pivoted at one end by an adjustable pivotal connection, and having an opening at its lower side at the opposite end, through which the ball normally projects, the adjustable valve f! and cord 2, substantially asdescribed.
